A sweep conveyer 7, which feeds material to an outlet in the base 2 of a storage structure such as a silo 1 and is at the same time swept over the base by rotation about a vertical axis, has its drive coupled to that of a fixed discharge conveyer 9 by which the material emerging from the outlet is carried away. The coupling comprises gearing within the interconnected housings 19, 62 whereby on driving the conveyer 5, e.g. by motor 6, the drive may be transmitted both to drive the conveyer 7 and also to rotate the upper housing 62 carrying the conveyer 7 with respect to the fixed lower housing 19 carrying the conveyer 5. Each of the conveyers comprises a screw and, as shown in Fig. 3, the shaft 16 of the lower screw has a splined extension within the housing 19 on which extension a collar 30 is slidably mounted, which collar terminates in gear-teeth 28. When a clutch rod 41 (Fig. 2) is suitably operated these teeth engage a gear member 29 which in turn drives a further gear element 49 about a vertical axis. The rotation of gear element 49, by engagement with bevel gear 71, drives the shaft 66 of the upper screw 65 comprising the sweep conveyer 7. The rotation of gear element 49 is also used to rotate the upper housing 62 on the lower housing. In the form shown this rotation is obtained by supporting the upper housing on an annular friction plate 76 secured to the gear element 49 and resting on the lower housing 19. In another form, Figs. 6 and 7 (not shown), a planetary gear system replaces this friction plate. U.S.A. Specifications 2,233,085 and 2,275,558 are referred to.

Lifting apparatus 1 comprises a lower casing 2 and a lifting casing 3 containing a conventional hydraulic lifting jack 4 with a cylinder 5 and a piston 6 extended by operating a spring-loaded plunger 15 by a pedal 19. As shown in full lines in Fig. 1, the pedal 19 is prevented from being depressed by a cross-bar 36 on a counterhold 33 pivoted at 32 to the casing 2. A handle 34 acts as a carrier for the apparatus when the counterhold is in this position. A sliding stabilizer 22 can be extended and retracted by a control lever 27 which engages, through a coupling ball 26, a slot 25 in a fork 24. To lift a load (not shown) the counterhold 33 is folded down from the carrying position and the operator, keeping one foot on the counterhold 33 presses repeatedly on the pedal 19 over short strokes which do not engage the lever 27. When lifting claw 11 has risen sufficiently for the stabilizer 22 to be extended beneath it, Fig. 2 (not shown), the pedal 19 can be pushed down to the position 1911, Fig. 3, thereby extending the stabilizer 22 in the direction of arrow 23. The counterhold 33 can now be released. When the jack is retracted a stop 31 on descending casing 3 resets the stabilizer 22 in its initial position, before the claw 11 has reached the ground, by pivoting the lever 27 back to its initial position through striking cam 30. The initial position of the claw 11 may be adjusted over a range of heights by using an attachment 38, Fig. 4, extending upwards from the lifting casing 3 and provided with a number of keyhole openings 45 to receive mounting element 13 on the claw 11.
